General Information
Term external sensory organ precursor cell IIa ID (Ontology) FBbt:00005166 (Fly Anatomy)
Definition Second-order precursor cell that develops from an external sensory organ precursor cell I. In the microchaete lineage, it divides to give rise to the tormogen cell and the trichogen cell of an external sensory organ (Gho et al., 1999; Hartenstein and Posakony, 1989). In the development of antennal olfactory sensilla, it produces two daughters, pOa and pOb, which each divide asymmetrically to produce the four types of support cell per sensillum (Endo et al., 2012; Chai et al., 2019).[ FlyBase:FBrf0049554 FlyBase:FBrf0111371 FlyBase:FBrf0217319 FlyBase:FBrf0241429 ]
Also Known As "pIIa" ; "SOPIIa"
